I'm hoping we see a move to allow the rendering of the webpage to be entirely up to the users. Just provide the data, and let me decide how I want to interact with it. But that would ruin SEO and Ads, so we're gonna get in a buncha legal battles about web scrapers instead.
But reader mode is mostly bunch of heuristics with tons of ad-hoc special cases and hacks instead of relying documents to be well-structured. So in many ways it is the opposite of successful example.
